I think what he meant by "drawer pull" rule is that he hoped someone would have tackled this issue in the past and would have an applicable rule they could share, as if they just pulled an applicable solution out of a drawer. And yes, we've covered some CGA via the tutorials and through working with Patrick, and most of us have written a few rules from scratch, but this is a bit more complex and we've only been working with CGA for the last few months, so it's all pretty new. The rail rules I've found so far create something more akin to a heavy rail line, not just tracks set into a roadway, and I was looking specifically for help in how one would go about incorporating them into a road rule. Doing tutorials and watching someone else work on parameters in an existing rule set is a bit different from trying to conceptualize and execute this sort of rule from scratch.

I’m working on some of the finishing touches for my model of the Germantown section of Philadelphia and it was brought up this week that I should look into trying to recreate the unique surface of Germantown Avenue, which includes a pair of trolley/streetcar lines running along the centerline with Belgian Block (ie. setts) lining the outer 1/3 of the roadway and generally accounting for the parallel parking lane: https://www.google.com/maps/@40.035426,-75.174236,3a,75y,324.73h,71.95t/data=!3m4!1e1!3m2!1sMrK6vhAFiqhYenuaa8vX3w!2e0!6m1!1e1?hl=en I found a similar type of sketchup model using useful textures on 3DWarehouse, but the Belgian Block is in the middle of the tracks and the concrete is on the outside…just the opposite of the situation in Germantown: https://3dwarehouse.sketchup.com/model.html?id=ub75d5171-aedc-4129-86b6-0a8cb14dd676 I’ve looked through the existing rail rules and can’t find something I could easily modify to serve this purpose, and my CGA skills aren’t strong enough for me to attempt writing a rule from scratch that could be applied to the street centerlines…or better yet, be a street texturing option within the Complete Streets rule. Would any of you be able to help? (Our professor expressed hope that one of you may have a “drawer pull” rule written for just such a situation that I could use or modify) Thanks so much in advance…I’m at a bit of a loss here. -Michael Gall Graduate Assistant MS in GeoDesign ’15 Philadelphia University

I downloaded the most recent 2014 Redlands examples and ran into the same problem (ie. no start rule). When I reverted to a version of the 2014 Redlands rule files from a few months ago, it worked without issue...and the weird thing is that I see no appreciable difference between the two.
